Key steps towards the realization of a high-precision optical clock based on Ni¹²⁺

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

NIST set its new atomic clock in motion, and it’s astoundingly precise

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

To explore deep space, scientists say we'll need better clocks. Here's why

It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend ...

NIST set its new atomic clock in motion, and it’s astoundingly precise

The clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say. A new atomic clock is one of the world’s best timekeepers, ...
